CUPERTINO, Calif., Aug. 15, 2022 — Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) (“Reviva” or the “Company”), a clinical-stage pharmaceutical company developing therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), cardiovascular, metabolic, and inflammatory diseases, today reported financial results for the second quarter ended June 30, 2022 and summarized recent business highlights.

“This quarter our focus remained on further advancing the clinical development of our lead asset, brilaroxazine, in the ongoing pivotal Phase 3 RECOVER study to assess the safety and efficacy in patients with schizophrenia,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “With over 20% of the approximately 400 patients planned already enrolled, we remain on pace across the 15 sites in the United States, and we anticipate an acceleration in enrollment with the initiation of additional sites in Europe and India by the end of September.”

Dr. Bhat added, “We believe brilaroxazine has broad therapeutic potential beyond schizophrenia, and we continue to actively explore non-dilutive financing opportunities, including partnerships, to support expansion into other indications arising from underlying dysfunction in serotonin and dopamine signaling including attention deficit hyperactive disorder (ADHD) and pulmonary arterial hypertension (PAH), as well as bipolar disorder, major depressive disorder (MDD), and idiopathic pulmonary fibrosis (IPF).”
